    Everything is great, for price it does its job well. I love that there is spring in the middle so the speed is much faster than traditional ones with springs at the bottom. You will need more weight to hold the base down though

    I’ve owned the first MaxxMMA Reflex and the new Cobra Reflex and I love them both. After using the Cobra Reflex for about 2 months, I discovered a leak where you put the inflation needle. I contacted Eemore/MaxxMMA through their website in order to buy a new bag. They were prompt in responding and replaced my bag free of charge as they stated it was still under warranty. They shipped it within days! Really cool to experience such awesome customer care. Thanks to Woody and Eemore/MaxxMMA!

    Durability. I would like to mention the large bag had a small hole in it and would not stay inflated. Great customer service. I contacted them and they contacted me immediately with replacement. We love the small bag and can’t wait to receive the large one. Thank you

    High quality and super easy setup The top pole was a little loose and clanked against the other metal pole so I put a piece of tape below the button and it works perfectly now

    Golden Review Award: 3 From Our UsersExcellent product for my needs and a lot of fun to use. Great workout.

    I’m not a heavy user, only one or two workouts per week, but it’s been perfect for me. It’s another bag that I can’t walk past without stopping to hit it a few time.

    Set up was easy. What took longest was filling the base with sand. The opening is very small and the sand backs up in the funnel constantly. Lots of tapping, poking, and shaking involved in the process. I read that sand is heavier so I went with that and got almost 50 lbs in the base. Then I filled large plastic bottles from the dollar store with sand and put them in the weight bag on top of the base. It’s very sturdy and doesn’t move.

    I saw people complain about hitting the edge of the plastic cup at the base of the bag. I wrapped mine with a foam weatherstripping from Lowe’s or Home Depot, then wrapped that with electrical tape. Easy to do and easy to replace when it wears out. It hasn’t come loose or worn out yet for me.

    So far, it’s been excellent for me and I feel like I’ve already gotten my money’s worth. Great fun. Great workout.

    Excellent product for my needs and a lot of fun to use. Great workout.

    Great reflex bag for the price. I’ve had it for two months now and have been putting in work 6 days a week. I like the fact that you have 4 settings of rebound that you can choose from. I’d recommend a few things to you should do to get it to work properly.
    1- Put blue removable lock tight on the base bolt so it eliminates problem of getting loose and causing unwanted vibration.
    2- I filled the base with 50lbs of sand and water and filled the sand bag base with around 50lbs of sand and it still tends to lift off the ground when punching with power. I ended up buying a second sand bag base from the same company and filled it with another 50lbs of sand and now it does not move. 150lbs total. You can also use Olympic weight plates.
    3- Before each use make sure to tighten screw that sets the height of the bag as it will also tend to get loose.

    All in all it’s a great bag for the price compared to all the other reflex bags on the market.
    It’s a great tool to stay in shape, practice punch timing, slip and counter moves and precision.

    I think the reflex bag plus the stand is perfect with added weight attached to the base. I’ve hit the bag like crazy with hooks, over hands etc. Only thing that bums me out is the set came with a extra “bag ” which is smaller for jabs and I would’ve loved to use this but it came broken. The air “blow into ” piece was none existence . So now I have a reflex bag that can’t be inflated because it has a 3/8 in hole on the top that can’t close.

    Love this product. You definitely have to weight it down with extra weighted bag but it’s great for at home practice. Very easy to store away and keep out of the way.

    very sturdy base, which is what I was looking for.
    and very good customer service.
    I needed some help and a few extra parts and they were very responsive and easy to deal with.
    i recommend this if looking.

    Golden Review Award: 3 From Our UsersOverall – I am pleased with the product and very quick delivery. Assembly was easy and the product works as described. One problem however – the smaller bag was defective. It does not hold air. See image attached. The bigger bag is fine. I have contacted the seller and am waiting for a reply. I am new to boxing. But I had a lot of fun with this Cobra bag. Even got hit in the face once, when I did not move out of the way. Good lesson to protect your face and move. The longer swing is more fun and your chances of getting hit in the face are higher. The shorter swing is easier in a way, but faster return. I am looking forward to spending some quality time with this bag, in addition to my heavy punching bag, speed bag, double end bag and Mexican style double double bag. I think I should stop buying boxing equipment now and try to master what I have.

    I was hesitant to buy this because of some reviews but it was SO easy to put together and it works great! I put sand in the stand and inside the extra bag it gives it to weigh it down. The only confusing part was how to switch the spring settings. I figured out that the hard tube goes into the pole which changes the spring.

    As advertised! No complaints! I filled to the maximum with sand. Made my height adjustments. Selected the ball of choice. And it has become an everyday item of use. Extremely satisfied with this product. I can land my punches, uppercuts, hooks, knees, elbows, and kicks!!! It is amazing for accuracy, hand eye coordination, dodge reflexes and more. As you work out with it, you’ll personally add and create new workouts to fit you personally.

    Golden Review Award: 38 From Our UsersA lot of the review are because the base will not stand still. Well the problem is you are using water! Sand is needed for the base and weight bag. Strongly recommend. I used Play Sand from Lowe’s. $5 per bag. I purchased two. One other thing is the directions for the speed adjustment is a little tricky. Speed 1 & 2 are the two different bags. The big bag is Speed 1, and the small bag is 2. The other speeds you have to put the adjuster inside of the spring (BLACK CUSHION). Then the big bag is 3, and the small is 4. I hope this helps out. I love the bag, honestly everything I expected. I hate when review are bad because of user error. I would recommend this to my whole family!

    Golden Review Award: 23 From Our UsersWhen I started using the bag the first thing I noticed is how impossible it is to keep the in place. I filled the base full of water, put 60lbs of dumbbell weights in the bag on top, and it still moves every time I hit it. This makes it too loud to use indoors/upstairs. I have to lug it down to my apartment’s tiny gym.

    After a couple uses, I noticed that there was water on the floor underneath the base. The carpet I set it on overnight was soaked in the morning. I figured there was a tiny leak, but I didn’t want to pack it all up and send it back, so I used a little dab of sealant and by morning it was fixed. It was disappointing and if the leak were any bigger, I would have sent it back right away. But I was having fun and didn’t want to stop.

    The next thing that I found out after a couple more uses was how it cuts my knuckle open every session. The plastic that secures the bag to the pole, It’s not sharp, but if you hit it hard enough it will gouge a chunk out of your knuckles. And just about every time I use it I get cut open in the same spot, so the wound never fully heals. It becomes painful after a while. Blood gets all over my clothing, gym, and bag. It’s very annoying. The gloves they provide are comfortable and fit well, but they are cut offs and don’t protect your knuckles. I don’t have a set of full gloves and I prefer using the MMA ones, but it’s not worth getting cut open so often. I’ll have to pony up for a set i guess.

    I kept using it a couple times a week and regardless of the negatives, I have a lot of fun on it. It’s only limited by your imagination really. I put it on the fastest setting and it really challenges your speed and timing. If you put it on the slow setting, it will swing back far enough to work on slips. It’s a great tool to have in your repertoire, and it’s fun, which is why I was so disappointed about what happened next….

    After 8 months of regular use the little screw that secures the pole to the base snapped! And then it was all over….
    The little screw broke off into the pole and it won’t come out. The screw and the bottom pole has to be replaced. IF the screw was larger in diameter, I believe it wouldn’t have broke, at least not til much later. It’s a major design flaw that maxxmma should and can easily fix.

    I tried emailing MAXMMA three or four times with no response. So I looked through the reviews and found some other people have had these same problems, and in the comments there was a response from the distributor asking to send a pic of the broken piece and they will replace it. SO I just called the number that was listed, and what do you know, they said they would send out the replacement parts right away. I SHOULD get it in a few days since the shop is a couple hours from my apartment. I will update this when I get it.

    In conclusion, It’s a very fun piece of equipment, worth every penny. The time I enjoyed on it largely outweighs the negative things I’ve listed. There are a few things they need to fix in the design, but if they do the right thing, after that it should be just as good as some of the higher priced cobra bags out there.

    My boxer son has advanced and the mid range spring makes the response time faster. Has 2 bags, one smaller. Note that large bag split near plastic base and company replaced for us immediately. Plastic base bothers my boxer sometimes. Pleasure to work with this company.

    Golden Review Award: 6 From Our UsersThe thing I was worried most about was whether or not I’d be knocking it over or moving it all around the floor hitting this bag.

    Well, I bought two 50 lb bags of sand for about $3 each and a funnel, filled up the base and filled up the weight bag that comes with it and stacked it on top of the base. I’ve been wailing on this bag and it hasn’t moved an inch. Good stuff. We’ll have to see how long it holds up but first impressions are really solid.

    ot a boxer but i think i’ll learn the basics with this bag for self defense. loaded the weight bag with water bottles, 2 5lb dumbell weights, and some smooth rocks. gloves are sweet but they don’t have padding on the outside of the thumb. this is one of the best purchases iv’e made on amazon.

    Golden Review Award: 2 From Our UsersThe Cobra reflex bag is awesome and fun to workout with. No time was wasted because of its easy setup. I filled mines up with sand as it’s heavier and because water evaporates over time. I enjoyed the quick spring-back action that the Cobra reflex bag provides. Each punch/kick you throw at the Cobra reflex bag is returned quickly with the same amount of force. It’s great that you can increase the tension on the Cobra reflex bag to provide quicker speed. This make the workout fluid and fun and improves your hand-eye coordination. I would definitely recommend this to a friend.

    Golden Review Award: 4 From Our UsersSo far so good. It’s not meant to be wailed on like a heavy bag but rather designed to work on speed and timing. In that regard it appears to be holding up well. Only time will tell but so far I am optimistic. If it last at least a couple of years I will come back and give it the fifth star. You will definitely need extra weight if you only fill the base with water. I happened to have an extra power rope that I coiled up around the base and it is very secure.

    Golden Review Award: 6 From Our UsersIt’s really good but not heavy enough without the weight bag. I had to put so many weights in the bag to make it stand still when I punch it. Also really noisy but other than that it’s alright. The punching gloves that it comes with is perfect and it protects your hands really nicely.
